JOHN D. WILBER, OF TOWANDA, PENNSYLVANIA.

MOWER.

SPECIFIGATION forming part of Letters Patent No. 225,960, dated March 30, 1880.

Application filed May 6, 1879.

To all 'whom it may conoem:

Be it known that I, JOHN -D. WILBER, of Towanda, in the county of Bradford and State of Pennsylvania, have invented a new and useful Improvement in Mowing-Machines, of which the following is a specification.

This invention relates to certain novel improvements on the mowing-machine for which Letters Patent of the United States were granted to me bearing date, respectively, on the 19th day of February, 1863, the 5th day of April, 1870, and on the 16th day of September,1873,wherein the cutting apparatus is applied on the ends of diverging arms extending out in front of a two-wheeled draft-frame, having thel horses spread wider apart than the cut.

Figure l is a longitudinal section, and Fig. 2 is a plan view, of the improved machine without the gear mechanism, cutting apparatus, and driverls seat.

Similar letters of reference indicate corresponding parts in the several figures.

The following description will enable others' skilled in the art to understand my invention.

In the accoinpanying drawings, A A represent two transporting- Wheels, which are mounted on an axle, B.

O represents the pole, with'a broad platform for sustaining the driver, which is connected loosely to the axle B by means of eye-bearnigs.

D represcnts the rect-angular frame of the machine. Beyond the front ends of this frame eXtend two arms, which are curved outward, and have connected to their front ends two shoes, E Ef. In shoe E is secured a stud or pin, a, on which vibrates the bent arm or rockshaft F. i

The pitman is attached to the upper and inner end of the rock-shaft by a ball-and-socket `joint.

The lower arm of rock-shaft F has a hollow extension at an angle of sixty (600) degrees, or thereabout, to the rock or stud pin a, for the purpose of having the two connectionsthe one with the pitman, the other with the cutter-both on the same horizontal plane. Within said hollow extension is a hollow journal (shown in dotted lines) having both arollingV and a longitudiual reciprocating motion. Through this joint, at right angles, there is a hole, in which a pin is inserted. Both parts of this joint extend in front of the pin, thereby lessening the tendency to wear andproduce the lost motion that occurs when the usual joint is used.

The shoes E E' carry supporting-wheels G G' The wheel G is located in advance of the finger-bar, in order to give the proper play to the rock-shaft F. The wheel G' is located so as to extend back and overlap the shoe E' and the finger-bar, bringing its axis on a line with the work done by the cutter and nearly under the line of the finger-bar, thns avoiding the tendency to torsional strain that obtains when the wheel is in advance of the bar and its side arm is jointed to the frame.

On the rear end of the pole and platform O is attached the foot-lever H, arranged with a lever, h, Operating upon the frame D, in rear of the axle B, thereby allowing the driver with his foot to relieve the pressure of the bar on the ground when working, or to assist in raising the bar when desired.

On pole O, in advance of the platform, is secured a two grooved or slotted plate, I, upon which slides a pronged hasp-iron, for retaining the double-tree in place. The hasp-ironz' is secured to the plate I by two bolts, whose heads are held in and below the grooves or slots in the plate I. Thus the double-tree and hasp t' are allowed a limited sliding or forwardand-back motion, and then arrested by the two bolts and the termination of. the grooves or slots in the plate I.

What I claim as lny invention, and as an improvement in harvesters, and which I desire to secure by Letters Patent, is-

1. The rock-shaft F, having its lower hollow arm on an angle of sixty degrees, or thereabout, to its rock-pin, which is at right angles to the side arm and shoe, upon which it is located, said arm containing a knife-pin barrel having a transverse hole through it to receive the knife-pin7 and both the hollow arm the driver can7 While niowing, easily relieve and the knife-pin barrel projecting in front of the down-pressure of the forward end of the 10 the knife-pin, snbstantially as shown and deframe caused by the gear niechanisln, substanscribed. tially as deseribed.
